UPDATE:Bonnie Raitt has canceled the first leg of her previously announced joint tour with James Taylor due to an unspecific medical condition. According to a statement posted on the singer’s Facebook on Monday, Raitt recently learned after a routine physical that she will soon need surgery; her prognosis is good, and a full recovery is expected.

Sheryl Crow will now join Taylor as a “special guest” for his concerts in Phoenix (May 29th) and L.A. (May 31st, June 1st). The first leg of the tour, which launches May 8th in Jacksonville, Florida, will now be dubbed an “Evening With James Taylor & His All-Star Band” and feature two sets with a brief intermission.

“I’m deeply sorry to have to disappoint my fans, James and colleagues with these cancellations,” Raitt wrote. “I was so looking forward to our tour, but I’m very grateful that the doctors feel this can be taken care of with surgery. Im feeling strong and am in great hands with my wonderful team. I fully expect to return for the second leg of the U.S. tour in June followed by our European tour in July. Thank you all for your concern and understanding that the best gift you could give me is respecting my wish for privacy and giving me space to heal. Can’t wait to see you all back on the road again soon!”

Ticket buyers seeking a refund from a show affected by the cancelation are instructed to contact the original point of purchase. Those who purchased tickets via the artists’ respective sites can do so by emailing tickets@BonnieRaitt.com or tickets@JamesTaylor.com.

“This summer was to be Bonnie’s and my second summer touring together,” Taylor said in a statement on his website. “We wanted to do it again because it was such good fun the first time, we didn’t want it to end. We are so looking forward to having her rejoin the tour in mid-June. Of course, there is no question as to the priority of your health, Bonnie. You will be constantly in our hearts and minds until we see you in June.”
